摘要
北秦岭存在A、B、C三类火山岩系列,对应着幔源型、壳幔混染型和壳幔混合型成因类型。火山岩系列和成因类型的系统变化,反映了多旋回壳幔物质迁移特证。
In the Northern Qinling Mountains there are three igneous rock series: A, B and C series, corresponding to the mantle-derived, the mantle-derived magma contaminated by crust materials, and the crust-mantle mixing genesis types. The systematic changes of the igneous rock series and the genesis types have reflected polycyclic transference features of the crust and mantle materials.
